It's time to do some detail in the scales but first I wanted to test a couple settings.
Below shows 2 size ball mills and a spot drill at different depths. A 90 degree spot drill is often used for edge milling chamfers, engraving and in this case cutting a "slot". The are 2 flute and can be run with a chip load several times higher than most other end mills. I find myself using it more and more all the time.
I am looking for how the colors showed up in this multi-layer Ultrex g10.
The colors are black and red and each layer is around .015" thick.
I was pretty sure the ball mills would be the way to go but I found I preferred the spot drill somewhere around .025" deep.
The difference isn't just the appearance, it's the feel as you drag your finger across each one. The ball mill cuts all felt sharp, the spot drill not as much.
The spot drill also seemed to show the color a little better.
I'll try a combination of both in the .015" to .03" depth range.
Doug stopped by for peanuts the squirrels have buried in the snow.
